This application is a Divisional, the disclosure of which claims the benefit of priority from parent application number U.S. Ser. No. 15/480,482 filed on Apr. 6, 2017.

FIELD OF THE INVENTION

The present invention relates to the field of agrochemical compositions and formulations. In particular, the invention provides a composition comprising a tetraniliprole alone or in combination with other plant protection agents suitable for controlling rootworm larvae in soil.

BACKGROUND OF THE INVENTION

Insects and plant pests cause millions of dollars worth of damages annually on agricultural products. Rootworms are one of the major agricultural pest insects contributing to the damages to agricultural products. These pests have a wide range of host plants and in their larval form make tunnels through the roots of young plants, stunting or killing them. They are typically native to the soil and will readily infest a field of crop plants, most notoriously corn. These pests include but are not limited to such species as Diabrotica virgifera virgifera (D. virgifera), D. undecimpunctata undecimpunctata (D. undecimpunctata), D. barberi, D. u. howardi, and D. u. tenella. Some are perennial pests of corn across most of the Corn Belt. Despite ongoing new pesticides and insecticides, resistance continues to emerge among such pests as D. virgifera, D. undecimpunctata, D. barberi, D. u. howardi, and D. u. tenella. Thus, there is a need for new techniques and compositions to combat such species of pests.

SUMMARY OF THE INVENTION

One aspect of the present invention provides compositions that exhibit enhanced activity against rootworms in their larval form. Another aspect of the present invention provides novel methods for controlling rootworms.

In one embodiment, the compositions of the present invention contain an effective amount of a diamide insecticide as the sole active ingredient. In this embodiment, the diamide insecticide includes but is not limited to tetraniliprole, chlorantraniliprole, flubendiamide, and cyantraniliprole. In certain embodiments, the diamide insecticide is tetraniliprole.

In another embodiment, the composition may further contain a plant protection agent selected from the group consisting of pesticide, arthropodicide, insecticide, acaricide, nematocide, fungicide, herbicide, plant growth regulator and a combination thereof.

DETAILED DESCRIPTION OF THE INVENTION

Various embodiments of the present invention provide an agricultural composition for controlling rootworms. At least one aspect of the present invention is directed to the novel discovery of compositions containing diamide compounds that exhibit potent activities in controlling and suppressing rootworm pests, particularly in their larval form. Even more surprising and unexpected is the activity spectrum of tetraniliprole against these pests.

As used in this specification and unless otherwise indicated, the term “rootworms” includes but is not limited to D. virgifera (also known and refereed herein as Western corn rootworm “WCRW”), D. barberi (also known and referred herein as Northern corn rootworm “NCR”), D. u. howardi, D. u. tenella, and D. undecimpunctata (also known and referred herein as Southern corn rootworm “SCRW”).

As used in this specification and unless otherwise indicated the term “plant protection agent” refers to a molecule or combination of molecules which express biological activity as a pesticide, arthropodicide, insecticide, acaricide, nematocide, fungicide, herbicide, plant growth regulator or a combination of two or more of these biological activities.

As used in this specification and unless otherwise indicated, the term “controlling” refers to reducing, inhibiting, or eliminating the presence of rootworm species during one or more of its growth stages. For example, the compositions of the present invention may be used for controlling the growth of rootworms at any instar stages as well as its pupil and adult forms.

As used in this specification and unless otherwise indicated, the term “insecticide” refers to a molecule or combination of molecules that repels, retards, or kills insects, and can be used for plant protection, edifice protection, turf protection, or protection of a person.

The term “liquid fertilizer” refers to a fertilizer in a fluid or liquid form containing various ratios of nitrogen, phosphorous and potassium (for example, but not limited to, 10% nitrogen, 34% phosphorous and 0% potassium) and micronutrients, commonly known as starter fertilizers that are high in phosphorus and promote rapid and vigorous root growth. Liquid fertilizers are commonly aqueous-based. As used herein, the term “aqueous-based” indicates that the predominant solvent or vehicle is water. The term “ambient temperature” as utilized herein shall mean any suitable temperature found in a laboratory or other working environment, and is generally not below about 15° C. nor above about 30° C.

The modifier “about” is used herein to indicate that certain preferred operating ranges, such as ranges for molar ratios for reactants, material amounts, and temperature, are not fixedly determined. The meaning will often be apparent to one of ordinary skill. For example, a recitation of a concentration of about 200 grams per liter in reference to, for example, a formulation would be interpreted to include other like concentrations that can be expected to provide similar effect for the concentration, such as 180 grams per liter or 220 grams per liter. Where guidance from the experience of those of ordinary skill is lacking, guidance from the context is lacking, and where a more specific rule is not recited below, the “about” range shall be not more than 10% of the absolute value of an end point or 10% of the range recited, whichever is less.

In one aspect of the present invention, novel compositions are described for controlling rootworms that contain at least one diamide compound selected from the group consisting of flubendiamide, chloranthraniliprole, cyanthraniliprole and tetraniliprole in a carrier system in amounts effective to inhibit the infestation of the larvae in a location of interest. In at least another aspect of the invention, combinations of a diamide compound with one or more plant protection agents are described to broaden the spectrum for insecticidal efficacy.

In another aspect of the present invention, methods for controlling infestation of Diabrotica larvae in a location of interest are described. In at least one embodiment, the controlling of larvae results in at least 60, 70, 80, 90 or 100% inhibition of larvae in such location. According to certain embodiments, methods of controlling infestation Diabrotica larvae at all its life stages can be achieved by applying a composition comprising a diamide compound selected from the group consisting of flubendiamide, chloranthraniliprole, cyanthraniliprole or tetraniliprole and a carrier system in amounts effective to inhibit the infestation of the larvae in a location of interest. In another embodiment, the diamide compound is tetraniliprole.

In another embodiment a method for controlling infestation of Diabrotica larvae in a location is described comprising (a) applying an amount of a composition comprising a liquid agricultural formulation comprising an active ingredient selected from the group consisting of flubendiamide, chloranthraniliprole, cyanthraniliprole and tetraniliprole and an agriculturally suitable carrier system in amounts effective and optionally a plant protecting agent, and (b) inducing mortality in at least 60% of said larvae. In one embodiment, the larve mortality rate is in at least 70%, 80%, 90%, 95%, 98%, or 99% in such locations. In at least one embodiment, the location of interest is on the plant itself, plant seed, plant roots, plant part, foliage, seedling or substrate for growing the plant or crop. In another embodiment, the larvae is NCR, WCRW, SCRW, or a combination thereof.

In at least another embodiment, the methods according to the present invention provide greater control at all instar stages of rootworm larvae as compared to other diamide insecticides such as chlorantraniliprole flubendiamide, and cyantraniliprole at a comparable rate of administration to the soil or the area of interest. In at least one embodiment, a tetraniliprole containing composition according to the the present invention unexpectedly provides a statistically greater control of SCRW and WCRW as compared to cyantraniliprole and chlorantranilipole. In another embodiment, the tetraniliprole containing compositions of the present invention are administered at ranges between 2.5 to 100 g ai/ha, or 7.5 to 60 g ai/ha to provide a larval mortality rate of at least 60%, 70%, 80%, 90%, 95%, 98%, or 99% in administered locations.

For example, both direct spray and foliar applications can effectively control the egg production on the plant. Certainly, the method of the present invention is by no means limited to plant foliage application; other processes such as soil treatment and seed disinfection are also contemplated within the scope of the present invention. In one embodiment, the targeted pests are any WCRW and SCRW and their adult forms.

Prior to application, the concentrations of the compositions may be readjusted. For example, tetraniliprole and the plant protection agent may account for about 0.0005 to 40% by weight in the composition. Other exemplary ranges include about 0.05 to about 10%, about 0.1 to about 10%, about 0.5 to about 10%, about 1 to about 10%, and about 1 to about 5%.

In certain embodiments, tetraniliprole and the plant protection agent may be applied at a rate ranging from about 1 to 20 gallons per acre. Non-limiting examples include about 1, about 2, about 3, about 4, about 5, about 6, about 7, about 8 and about 9 gallons per acre.

As described above, tetraniliprole and the plant protection agent may be mixed together and applied in the same formulation. Alternatively, tetraniliprole and the plant protection agent can be applied sequentially. The length of the interval between the applications depends on factors such as the target pest and concentration of the ingredients and can be determined by one of ordinary skill in the art without undue experimentation.

The plants to be protected by the compositions of the present invention include, for example, agricultural crops, fruit trees and trees other than fruit trees, grass crops, and weeds. The plants can be, for example, floricultural plants, and ornamentals. Examples of agricultural crops include, but are not limited to, corn, peanut, alfalfa, rice, wheat, barley, rye, oats, sorghum, cotton, soybean, pin-nuts, buckwheat, sugar beet, rapeseed, sunflower, sugar cane, tobacco, etc., vegetables; Solanaceae vegetables (eggplant, tomato, pin-Man, peppers, potatoes, etc.), Cucurbitaceae vegetables (cucumber, pumpkin, Zucchi-two, watermelon, melon, etc.), cruciferous vegetables (radish, turnip, horseradish, co-Rurabi, Chinese cabbage, cabbage, mustard, broccoli-, cauliflower-, etc.), Asteraceae vegetables (burdock, garland chrysanthemum, A-Ticho-clause, lettuce, etc.), Liliaceae vegetables (leek, onion, garlic, asparagus), Umbelliferae vegetables (carrot, parsley, celery, parsnip, etc.), Chenopodiaceae vegetables (spinach, Swiss chard, etc.), Labiatae vegetables (perilla, mint, basil, etc.), strawberry, sweet potato, yam, taro, etc., flowers, and foliage plants.

Such compositions may further include phosphate ester dispersants selected from a nonyl phenol phosphate ester and a tridecyl alcohol ethoxylated phosphate potassium salt. The dispersant or dispersants are preferably present in a total concentration of from about 0.02% by weight to about 20% by weight based upon the total weight of all components in the composition.

In one embodiment, the compositions of the present claims are superior in controlling rootworms as compared to diamide standards such as Exirel® (cyantraniliprole) and Coragen® when applied as a soil treatment against all stages and types of rootworms, particularly SCRW and WCRW larvae. In one embodiment, the tetraniliprole SC formulation of the present invention at ranges between 150 ppm to 250 ppm, preferably 200 to 225 pm and more preferably at 213.8 ppm, provided more than 90% control to larvae and provided statistically greater control compared to all rates of Exirel (cyantraniliprole).

In at least one embodiment, the viscosity of the formulation is adjusted to the speed of the apparatus to provide optimal foaming at a range of speeds including approximately 4-16 ounces of chemical formulation per acre, and 24-64 ounces of water per acre and a ground speed ranging from 2-7 miles per hour. In at least one embodiment, the present invention provides the delivery of the chemical formulation with at least 0.75 lbs a.i./gallon to be delivered at a rate of at least 0.25 gallons/acre. In at least one embodiment, the tetratranilipole containing formulation is administered at a rate of about 5 to about 100 g ai/ha or about 7.5 to about 60 g ai/ha. Another aspect of the instant invention provides a foamable formulation with an expansion factor of at least 30, 40, 50, or 60.

Suitable foam stabilizers act to stabilize the foam generated from the liquid, foamable formulation. Examples of suitable foam stabilizers include, but are not limited to, glycerine, Kelzan, carrageenan, xanthan gum, guar gum, gum Arabic, gum tragacanth, polyox, alginin, and sodium alginate. Glycerine and Kelzan are particularly preferred. The total concentration of foam stabilizers in the formulation will be dependent on the foaming agents used, and may comprise between 0.1% and 15% of the total formulation, preferably 1-14%, more preferably 7-12%.

The foamable formulations of the present invention may also include dispersants, and/or preservatives. Suitable dispersants include, but are not limited to, nonionic and/or ionic substances, for example from the classes of the alcohol-POE and/or -POP ethers, acid and/or POP POE esters, alkylaryl and/or POP POE ethers, fat and/or POP POE adducts, POE- and/or POP-polyol derivatives, POE-and/or POP-sorbitan or -sugar adducts, alkyl or aryl sulfates, alkyl- or arylsulfonates and alkyl or aryl phosphates or the corresponding PO-ether adducts, and mixtures thereox.

EXAMPLES Example 1: Determination of the insecticidal activity of Test Formulation in Midwestern soil

In this Example, a formulation according to the present invention provided greater control to 2^(nd) instar SCRW and WCRW larvae compared to the commercially available diamide standards, Exirel® (cyantraniliprole) and Coragen (chlorantraniliprole), when applied as a soil treatment.

Methodology

In order to induce seed germination prior to test initiation, corn seed was submerged in water for 12 h and then placed between layers of moistened paper towel for 48 h (FIG. 1A). Plastic Dart® containers (1 oz./30 ml) were utilized for the assay (FIGS. 1C-D). Treatments included Test Formula (tetraniliprole 200 SC formulation), Rugby® (cadusafos), and chlorantraniliprole. A 60 g ai/ha foliar rate applied at a volume of 30 GPA which equates to 213.8 ppm. If this application rate was condensed into a 6″ T-ban application that assumed a 30″ row spacing, the ppm rate would increase to 1069 ppm (213.8 ppm×5); thus, three rates were selected for all experimental and standard treatments (213.8, 534, and 1069 ppm).

Dilutions of Test Formula (Table 1) were mixed into dry, sifted, Midwestern soil (FIG. 1B), from Wyoming, Ill., by adding 49.5 mLs of solution into 330 g of soil and equated to approximate 15% soil moisture value; soil clumped when pinched.

An estimated 0.75 cm of treated soil was placed into the bottom of each container, two germinated corn seeds were placed onto the soil, and then the arenas were capped with a lid until rootworms were infested (FIG. 1C-D). Using a fine tipped paint brush, 5 larvae (2^(nd) instar) of each rootworm species (SCRW and WCRW) were transferred onto the soil of each replicate (FIG. 1E), covered with approximately 1.75 cm of treated soil, and capped (FIG. 1F).

There were 7 replicates and 35 larvae per treatment. Arenas containing soil, corn, and larvae were transferred into the Insectary room (≈23° C., 0L:24D) and evaluated 6 days later for the presence of living SCRW and WCRW larvae. Larvae not recovered within each arena were considered dead. Longest root for each seed was recorded. All data was analyzed by ANOVA/GLM with an alpha of 0.1 (Minitab 16.0). Data points having the same letter within each column are not significantly different and were assessed using ANOVA: GLM (α=0.1) (Table 1). The results are depicted in Table 1 below:

Note: Values in each column that have the same letter are not statistically different when analyzed at a 90% CI, ANOVA, GLM.

As indicated in the Table 1, in a rate to rate comparison, Test Formula provided greater control to 2^(nd) instar SCRW and WCRW larvae compared to the diamide standards, Exirel and Coragen, when applied as a soil treatment. Coragen did not provide adequate control to rootworm larvae at any rate tested. Against SCRW, Test Formula at 213.8 ppm (91.4%a) provided statistically greater control to 2^(nd) instar larvae compared to all rates of Exirel. Against WCRW, Test Formula at 213.8 ppm (94.3% control) statistically outperformed Exirel at 213.8 ppm (2.9%) and was numerically greater than Exirel at 534 (74.3% bc). All surviving larvae within Test Formula treated soil (213.8 ppm) were controlled, stunted, had not grown, and differed from all other surviving larvae within other treatments and rates.

CONCLUSION

In conclusion, against SCRW, Test Formula at 213.8 ppm provided some 91.4% control to larvae and provided statistically greater control compared to all rates of cyantraniliprole. Against WCRW, Test Formula at 213.8 ppm provided 94.3% control, and statistically outperformed cyantraniliprole. In fact, Test Formula of the present invention outperformed cyantraniliprole at 535 ppm.

Example 2

In this example, Test Formula was compared with Belt®, Coragen®, and Exirel® in both direct spray and foliar applications against SCRW and WCRW. The results indicated that the Test Formula provided greater control to SCRW and WCRW adults (direct contact and feeding). In addition, against SCRW and WCRW adults, Test Formula was more effective than Belt, Coragen, and Exirel in both direct spray and foliar applications against Southern and Western corn rootworm adults (SCRW+WCRW).

Methodology

Direct Spray: Three replicates of five adult beetles (n=15) were placed into 12 oz. Styrofoam containers on the day of application. Both southern and western corn rootworms (SCRW and WCRW) were evaluated in the bioassay. Treatments and rates are listed in Table 1 and were applied using a DeVilbiss sprayer in accordance with SOP 529.00 with the deviation of beetles being sprayed at 40 p.s.i.. Beetles were immediately transferred to clean containers and provisioned with a water source and a clipped cucumber leaf. At 2 Days After Administeration (DAA), mortality and % feeding damage were assessed. Because leaves varied in size, a single untreated check leaf was used as a reference to compare to all other replicates. After the initial assessment of feeding damage, the leaf was discarded and a freshly cut, untreated cucumber leaf was placed back into each arena. At 4DAA, mortality was recorded.

Foliar Spray: Four leaf staged cucumber plants were trimmed down to the two youngest leaves, the upper and lower leaves sprayed with the DeVilbiss at 40 p.s.i., and placed in the drying hood until dry. A single leaf was cut and placed over the water source within a 12 oz. Styrofoam container. Scissors were cleaned with 70% EtOH between treatments. Three replicates of five adult beetles (n=15) were infested onto the leaf of each container. Both southern and western corn rootworms (SCRW and WCRW) were evaluated in the bioassay. Assessment timing and methods were synonymous to the direct spray component of the assay.

The results of the direct spray applications are depicted in Table 2 below:

CONCLUSION Direct Spray:

SCRW: Against Southern corn rootworms, all rates of Test Formula (7.5 g to 60 g ai/ha) were statistically equivalent to Brigade and provided a greater level of control (86.7% to 100%) compared to the diamide standard products Exirel (8% to 20%), Coragen (0% to 13%), and Belt (0% to 8.3%) when applied directly to beetles. At 2DAA, no feeding on untreated leaves was observed on SCRW sprayed with all rates of Brigade. Feeding damage by SCRW beetles treated with Test Formula ranged between 0.0% to 1.7%, was statistically lower than Coragen and Belt, and numerically reduced compared to Exirel.

WCRW: Western corn rootworms were less susceptible to direct applications of all treatments compared to SCRW; at 60 g ai/ha, Test Formula provided greater control (72%) compared to the diamide standards, Exirel, Coragen, Belt. Feeding damage by WCRW beetles was similar to the SCRW data; beetles treated with Test Formula had feeding damage ranging between 0.0% and 1.3%, was statistically lower than Coragen and Belt, and numerically reduced compared to Exirel.

Foliar Spray:

SCRW: At 60 g ai/ha, Test Formula provided 48% control when sprayed to the foliage of cucumber plants compared to Exirel 7%, Coragen, 0%, and Belt, 0% . When Brigade treatments were removed from the statistical evaluation within Minitab, Test Formula provided statistically improved control compared to the standard diamides. Leaves treated with Test Formula had damage ranging between 1.3% and 3.3%, which was statistically lower than Belt, and numerically reduced compared to Coragen and Exirel. The amount of feeding damage was similar to the direct spray beetle component of the assay. Treated leaves were removed at 2DAA and replaced with untreated leaves; mortality would have likely continued to increase if the beetles remained on treated foliage.

WCRW: Similar mortality was observed between WCRW and SCRW infested upon Test Formula treated foliage. Accordingly the Test Formula provided 47% control vs. Exirel (27%), Coragen (27%), Belt (47%). The untreated check WCRW adults had 20% mortality at 4DAA, had the same mortality as the direct spray WCRW untreated checks, but were different cohorts. Brigade at the lowest tested rate (11 g ai/ha) had 40% recovery between 2DAA and 4DAA (60% mortality). Untreated check mortality, coupled with the low number of beetles per treatment (N=15), likely prevented statistical separation between treatments.

In conclusion, in both direct spray and foliar applications Test Formula provided statistically improved control compared to the standard product Belt and numerical and/or statically greater control compared to Coragen and Exirel.

Example 3

In this example, the activity of Test Formula treatment applied to Midwestern soil had extended residual activity against Diabrotica virgifera virgifera.

Methodology

Dilutions of Test Formula were mixed into dry, sifted, Midwestern soil (FIG. 1B), from Wyoming, Ill., by adding 300 ml of solution into 2000 g of soil and equated to approximate 15% soil moisture value; soil clumped when pinched. Treated soil was maintained in 3″ pots (8 pots per treatment) within greenhouse. Pots were watered from above one time per day to maintain soil at approximately 15% moisture.

An estimated 0.75 cm of treated soil was placed into the bottom of each container, two germinated corn seeds were placed onto the soil, and then the arenas were capped with a lid until rootworms were infested (FIG. 1C-D). Using a fine tipped paint brush, 5 larvae (2^(nd) instar) of each rootworm species (SCRW and WCRW) were transferred onto the soil of each replicate (FIG. 1E), covered with approximately 1.75 cm of treated soil, and capped (FIG. 1F).

There were 8 replicates and 40 larvae per treatment. Arenas containing soil, corn, and larvae were transferred into the Insectary room (≈23° C., 0L:24D) and evaluated 6 days later for the presence of living SCRW and WCRW larvae. Larvae not recovered within each arena were considered dead. All data was analyzed by ANOVA/GLM with an alpha of 0.1 (Minitab 16.0). Data points having the same letter within each column are not significantly different and were assessed using ANOVA: GLM (α=0.1). The results are depicted in Table 4 below:

CONCLUSION

Test Formula applied to soil maintained in fluctuating ambient conditions within the greenhouse at rates of ≥15 g ai/ha provided 97.5 to 100% control out to 43 DAT. The efficacy provided by the 2 lower rates of Test Formula were beginning to diminish at this time point. The lowest rate tested (3.75 g ai/ha) provided statistically reduced control (83% b) at 43 DAT. This break in treatment efficacy suggests that the product will ultimately break down in soil within a field setting.

Example 4

Soil treated with a formulation according to the present invention and maintained outdoors was evaluated for activity for WCRW larvae.

The efficacy of the formulation of the present invention on control of rootworm larve was evaluated after it was applied to soil and mainiained in natural ambient condiditon and was subjected to differing water pHs (6, 7, and 8) applied daily to soil.

Methodology

A solution of the Test Formula A was prepared by making dilutions in water to form a solution. Dry, Midwestern soil was brought up to 15% moisture with treatment solutions (Table 5). Buckets of treated soil were carted outside daily between Monday and Friday and exposed to direct sunlight. Carts were not wheeled out on days that forecasted precipitation. At the end of each day, soil buckets were brought back into the laboratory, weighed, the appropriate amount of water added to the soil to bring it back up to 15% moisture, and covered overnight; daily records of weights and amount of water added to each bucket was recorded. The deionized water (dH₂O) had a pH of approximately 5.0 and was altered with 0.5M KOH to a final pH of 6, 7, and 8.

At 30 DAT, 42 DAT, 57 DAT, and 85 DAT, 2^(nd) instar WCRW larvae were infested into treated soil containing and germinating corn seed and evaluated 6 days after infestation (6 DAI) for percent control and larval stunting. There were 6 replicates per infestation date with 5 larvae per replicate (n=30). Treatments applied to dry Midwestern soil for assessment of residual WCRW included Test Formula at 67, 267, and 1,069 ppm, Capture LFR at 1988.5 and 3,977 ppm.

Table 5 below provides the mortality rates of 2^(nd) instar WCRW larvae infested into treated soil exposed to direct sunlight at 85 days after treatment.

All three rates of tetraniliprole Test Formula as shown in Table 5 above, provided 100% control up to 42 DAT. The lowest rate of tetraniliprole (67 ppm) was further assessed at 57 DAT and 85 DAT. No statistical difference in the level of WCRW control was detected between tetraniliprole treated soil kept at 15% moisture using pH (6, 7, or 8) altered, deionized water (Table 5). At 57 DAT and 85 DAT, all surviving larvae recovered from Test Formula treated soil were severely stunted compared to the non-treated check (FIG. 2). At 85 DAT, Test Formula treated soil that had moisture maintained with water at a pH of 6 provided 97% control but was not significantly different from pH 7 or pH 8.

CONCLUSION

A solution containing tetraniliprole at 67 ppm (3.75 g ai/ha) was incorporated into Midwestern soil (15% moisture) and maintained outdoors provided control to WCRW larvae. This amount of tetraniliprole was equivalent to Capture LFR (α=0.1). Soil of each treatment was manipulated daily with water at pH 6, 7, or 8. A tetraniliprole conaining formulation according to the present invention provided ≥87% control with all surviving larvae being severely stunted compared to the non-treated check

Example 5: Efficacy of Test Formula treated soil against WCRW larvae

In this example residual activity and stability of tetraniliprole test treatments within microbially active Midwestern soil against 2^(nd) nymphal stage WCRW—Diabrotica virgifera virgifera was assessed in corn field and further compared to Capture LFR and Rugby.

Methodology

In order to induce seed germination prior to test initiation, corn seed was submerged in water for 12 h and then placed between layers of moistened paper towel for 72 h. Plastic Dart® containers (1 oz/30 ml) were utilized for the assay. Treatments included tetraniliprole Test Formula according to the present invention, Capture LFR® (bifenthrin), and Rugby® (cadusafos). A 60 g ai/ha foliar rate applied at a volume of 30 GPA equates to 213.8 ppm. If this application rate was condensed into a 6″ T-band application that assumed a 30″ row spacing, the ppm rate would increase to 1069 ppm (213.8 ppm×5). Five rates were selected for the experimental treatment (Test Formula) and compared to a single rate of two standard treatments (Capture LFR and Rugby). Treatment solutions (Table 4) were mixed into dry, sifted, Midwestern soil, from Wyoming, Ill., by adding 300 mLs of solution into 2000 g of soil and equates to approximate 15% soil moisture value; soil clumped when pinched.

An estimated 0.75 cm of treated soil was placed into the bottom of each container, one germinated corn seed was placed onto the soil, and then the arenas were capped with a lid until rootworms were infested. Corn was covered with approximately 1.75 cm of treated soil. Using a fine tipped paint brush, 5 WCRW larvae (2^(nd) instar) were transferred onto the soil of each replicate and then capped. There were 8 replicates and 40 larvae per treatment. Arenas containing soil, corn, and larvae were transferred into the Insectary room (≈23° C., 0L:24D) and evaluated 6 days later for the presence of living larvae. Larvae not recovered within each arena were considered dead. Additional treated soil was maintained within a 5 gallon bucket, covered with aluminum soil, and weights recorded. Additional water was added every Monday in order to maintain a 15% soil moisture level.

All mortality data was analyzed by ANOVA/GLM with an alpha of 0.1 (Minitab 16.0). Data points having the same letter within each column are not significantly different and were assessed using the Tukey Method (Table 5).

At 0 DAT: tetraniliprole treated soil at 30 and 60 g ai/ha provided 97.5% control to 2^(nd) instar WCRW. This bioassay confirms the activity of tetraniliprole against rootworms as shown in Example 1. Stunted larvae were detected in all tetraniliprole treated soils compared to the untreated check. At the lowest rate tested (3.75 g aiha), larvae were approximately half the size as the untreated check; a single, drastically stunted larvae were found at the two highest rates tested. Protection to the root and shoot system of corn was evident with all tetraniliprole treated soils (FIG. 3). The lowest two rates of tetraniliprole (3.75 g and 7.5 g ai/ha) were not infested at 14 DAT due to rates providing <80% control at 0 DAT.

At 14 DAT: The 15 g ai/ha rate of tetraniliprole formulation according to the present invention provided greater control at 14 DAT compared to 0 DAT. Those of ordinary skill in the art would understand that the lower rates (3.75 and 7.5 g ai/ha) at residual evaluation dates would be as effective in future assays.

At 28, 50, and 64 DAT: All soil treatments remaining in the bioassay provided ≥95% control out to 64 DAT (Table 6).

CONCLUSION

Tetraniliprole treated Midwestern soil (15, 30, 60 g ai/ha) maintained in the lab at a 15% moisture level provides ≥95% control to 2^(nd) instar WCRW larvae at 64 DAT. Both Capture LFR® (bifenthrin) and Rugby® (cadusafos) provided 100% mortality.
